Detailed description of the invention
With reference to figure 1, integrally indicated the pneumatic type beveling instrument or beveler that are incorporated to one embodiment of the invention by Ref. No. 20.Instrument 20 generally includes L-shaped shell 22, motor (substantially by 24 instructions) and cutting machine assembly (substantially by 26 instructions).The counterpart 30 being arranged on the upstream extremity place of shell 22 is suitable for being connected to traditional air hose (not shown), is described traditional air hose supply air from traditional air-source (not shown).Counterpart 30 is attached to shell 22 (such as, having screw thread), thus forms the import 32 of shell.Intake channel 34 extends between import 32 and motor 24, for by the air delivery from air-source to motor.Intake channel 34 comprises the shoulder 36 for receiving annular seal 38.The valve body 40 with center valve rod 42 is by coil spring 44 against seal 38 bias voltage, and described coil spring 44 is remained in intake channel 34 by counterpart 30.When valve body 40 is against seal 38, blocks intake channel 34, prevent air to be passed to motor 24 from import 32.When valve body 40 in passage 34 medium dip so when valve rod 42 is relative to intake channel skew (that is, angled), air freely enters motor 24 by valve body.There is provided the bar 46 extending through shell 22 to make valve rod 42 tilt and to open valve 40.Traditional flip-flop 48 is pivotally mounted on shell 22, for optionally advancing bar 46 to open valve 40.In the embodiment illustrated, spring Bias Safe part 50 splice closure 22 on trigger 48 is arranged on to prevent trigger from forcing down unintentionally and to open valve 40.Safety member 50 can against trigger 48 pivotable (counterclockwise rotating as shown), thus allow trigger to force down valve rod 42 is tilted and opens valve 40.
Motor 24 is arranged in shell 20.Motor 24 comprises cylinder (substantially by 60 instructions), and is rotatably installed in the rotor (substantially by 62 instructions) in cylinder.Cylinder 60 comprises housing 64, upstream end plate 66 and downstream end plate 68.Each end plate 66,68 keeps the ball bearing 70 of the minor axis 72 receiving rotor 62.Rotor 62 is held against the rotor blade 74 of the inner surface sealing of housing 64.The threaded cap 76 being fastened to shell 22 remains on through assembling motor 24 in the appropriate location in shell.Wear screw 78 to extend through shell 22 in the downstream end of intake channel 34 and proceed in shell to prevent motor 24.In other embodiments, imagination can use other secure component or block head cylinder and Shell structure without departing from the scope of the invention.
Cutting machine assembly 26 is fastened to bottom minor axis 72.Cutting machine assembly 26 comprises taper-cut chain-drive section 80 substantially, and described cutting machine head 80 has the little bearing 82 being arranged on its tip.As it will be apparent to those skilled in the art that, bearing 82 is useful in being positioned relative to just cut material by cutting machine head 80.Cutting machine head 80 comprises cutting machine mounting or the fixture 84 of three equi-spaced apart, and cutting machine 86 (such as, pottery beveler or round edge cutting machine) can as on cutting machine mounting as described in being arranged on screw fastener 88 or fixture 84.As it will be apparent to those skilled in the art that detachable cutting machine 88 in cutting machine rust or be damaged time allow that cutting machine is reorientated (that is, rotating).Threaded-on flange 90 is fastened to lid 76.When flange 90 rotates on lid 76, flange moves up and down relative to cutting machine assembly 26, for adjusting the depth of cut made by cutting machine assembly.Limit screw (not shown) is provided to rotate to prevent flange 90, thus the fixing maximum depth of cut adjusted.
As shown in Figure 2, lid 76 comprises the circumferential body 100 with top 102 and bottom 104.Top 102 comprises the internal thread (not shown) of the screw thread met on shell 22, for lid 76 being fastened to shell to be captured in shell by motor 24.The outer surface of lid 76 comprises puts spanner plane 106, for rotating lid when lid being attached to shell and being removed from shell by lid.Top 102 is separated with bottom 104 by step 108.The face of step 108 comprises the groove or slit 110 of allowing four equi-spaced apart that air transmits between described and contiguous ball bearing 70.Bottom 104 comprises the external screw thread (not shown) for flange 90 being attached to lid 76.
Fig. 3 illustrates the bottom plate 68 of the lower end minor axis 72 keeping ball bearing 70 and rotor 62.The internal diameter of plate 68 and face are suitable for keeping ball bearing 70.Separator 112 (Fig. 4) is provided in fix on center for by rotor minor axis 72 in end plate 68.The outer surface 114 of bottom plate 68 comprises the smooth table top (land) 116 of four equi-spaced apart, and described smooth table top 116 is allowed and transmitted between the aperture 118 of air when leaving cylinder in plate and shell 22.Common, the groove 110 in lid 76 and the platform 116 on end plate 68 form the part of exit passageway air being delivered to outlet 120 from cylinder 60.
As shown in Figure 4, between the table top 116 of the air leaving cylinder 60 on end plate 68 and shell 22, between ball bearing 70 and shell, through the groove 110 in end plate 68 and transmit cutting machine head 80 and lid 76.The lower end of the exit passageway between cutting machine head 80 and lid 76 forms outlet 120, and air is discharged through described outlet 120 after by motor 24.Cutting machine head 80 is positioned at the center of outlet 120, so exhaust is through cutting machine head 80 and circumferential surface, removes chip and other chip with the surface from material.By removing chip, the probability that chip affects movement of tool or destruction material is less.The part of the passage between end plate 86 shown in Figure 5 and shell 22.
When safety member 50 departs from and trigger 48 forces down, valve 40 is opened, thus allows that air is by intake channel 34, transmits towards motor 24.When air enters motor 24, the pressure differential of crossing over rotor blade 74 increases until rotor 62 rotates in cylinder 60.Cutting machine head 80 rotates with rotor 62 with rotary knife cutter 86.User advances cutting machine assembly ball bearing 82 and flange surface 120 abutting material, to locate and stabilizing tool 20.In addition, user is along the corner-moving instrument 20 of material.Cutting machine 86 scraping material, leaves little chip around cutting machine head 80.Outlet is advanced to along exit passageway by the air of motor 24.Blow away chip by the air of outlet from cutting machine head 80, prevent uneven cutting and material damage.
Now describe the present invention in detail, by aobvious and easy to know be when not departing from the scope of the present invention limited in claim of enclosing, modifications and variations are possible.
When introducing the key element of the present invention or its preferred embodiment, article "/one (a, an) " and " described (the, said) " mean to there is one or more key element.Term " comprises ", " comprising " and " having " be intended to comprising property, and be meant to there is other key element except institute's column element.
Because various change can be made to above structure, product and method without departing from the scope of the invention, thus meaning comprise in the above description and all the elements illustrated in the accompanying drawings all should be interpreted as illustrative and not there is limited significance.
